Hello,
I've a +28V DC output from a SPMS Buck converter with a ringing phenomenon of 2V peak (or 4V pk-pk) as could see in the attached.
I've tried using many methods like:
Unfortunately the results (as in the ringings) never change. Do anyone knows why?
The ringing period I've measured is about 80ns (hence about 12.6MHz).
What EMI block should I use? Anyone could help me?

I've tried using many methods like:
- RC snubber across switch node
- RC snubber across V(gs) or even V(ds)
